FRUSSONIA Flange Inserts 8 Pack 15/17/19/21mm – BPA Free Silicone

Elevate your pumping setup with FRUSSONIA Flange Inserts

Crafted to adapt 24 mm flange systems, the FRUSSONIA flange inserts come as an 8-pack with two inserts of each size: 15, 17, 19, and 21 mm. The design focuses on a sturdier wall and a shorter bottom edge to help create a reliable seal while keeping airflow smooth. The result is a cleaner, more consistent pumping experience without the frustration of frequent leaks.

What you get

• 8 pieces total, two of each size: 15, 17, 19, and 21 mm
• Broad compatibility with Momcozy, Spectra, Medela, Elvie, Lansinoh, and most 24 mm flanges
• Enhanced thickness paired with a shorter bottom for improved seal and suction efficiency

Why this matters

• Multiple sizes address variations in nipple size and changing fit over time
• Better seal and fit may translate to steadier suction during pumping sessions
• Wide brand compatibility gives you flexibility across popular pumps

Material and hygiene

• BPA free, food-grade silicone for safety and durability
• Recommended replacement every 1 to 2 months to maintain performance

Care and maintenance

Clean after each use with warm soapy water and rinse well. For deeper cleaning, you can sanitize at temperatures up to 100 C (212 F) for 5–10 minutes.

Usage notes

These inserts work with a wide range of pumping setups. If you already use a flange sizing kit, remember that measured values may differ from actual fit. Nipples can change over time, making multi-size options practical.
